People are being tricked into Facebook with the promise of a fun, free service without realizing they’re paying for it by giving up loads of personal information.

Most Facebook users don’t realize this is happening. Even if they know what the company is up to, they still have no idea what they’re paying for Facebook because people don’t really know what their personal data is worth.

The biggest problem, however, is that the company keeps changing the rules early on you keep everything private. That was the great thing about Facebook. You could create your own little private network. Last year. The company changed its privacy rules so that many things; your city, your photo, your friends’ names were set, by default (默认)to be shared with everyone on the Internet.

According to Facebook’s vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don’t share information. They have a “less satisfying experience.

Some critics think this is more about Facebook looking to make more money. In original business model, which involved selling ads and putting them. At the side of the pages totally, who wants to took at ads when they’re online connecting with their friends?

The privacy issue has already landed Facebook in hot water in Washington. In April. Senator Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set guidelines for social networking sites. “I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them,” Schrage admits.

I suspect that whatever Facebook has done so far to invade our privacy, it’s only the beginning,which is why I’m considering cancelling my account. Facebook is a handy site, but I’m upset by the idea that my information is in the hands of people I don’t know. That’s too high a price to pay.

While drunken driving may be on the decline, traffic safety experts remain puzzled over how to deal with another alcohol related danger: drunken pedestrians(行人).

Pedestrians struck and killed by cars often are extremely drunk. In fact, they are intoxicated(喝醉的) more frequently and with higher blood alcohol levels than drunken drivers who are killed in accidents, various studies have shown. Forty percent of adult pedestrians involved in fatal crashes have a blood alcohol level of at least 0.10 which by law in most states signifies intoxication compared to only 25 percent of drivers in deadly accidents, according to recent federal data.

Some types of pedestrain accidents have been declining nationally, especially those involving children, but the number of adult pedestrians who are drunk when killed in traffic has remained relatively steady at 2500 a year. The total number of pedestrians killed annually in U.S. traffic accidents is at least 7000, or one of every seven highway accidents resulting in death.

“We’re dealing here, we think, with a very severe drinking problem that leads to a severe highway safety problem,” said Richard Blomberg, president of Dunlap and Associates Inc, in Norwalk, Coon.

Blomberg, whose consulting company found a very high rate of alcohol involvement in a controlled study of pedestrian accidents in New Orleans, was among several researchers who spoke on the topic at the annual meeting of the Research council’s Transportation Research Board(TRB) in Washington in January.

Pedestrian accidents have not received enough attention in the past, according to Kay Colpitts, who chairs the board’s committee on pedestrians. Few methods exist to monitor walking habits, she said, and researchers have been mystified(迷惑不解) about how to prevent disasters.

Malls are popular places for Americans to go. Some people spend so much time at malls that they are called mall rats. Mall rats do not leave the shop until they drop in the hundreds of stores under one roof.

There are many places to go on safari(观赏野生动物)in Africa, but riding a horse through the flooded waters of Botswana's Okavango Delta must rank as one of the world's most exciting wildlife journeys.

Several safari camps operate as the base for this adventure, providing unique rides twice a day to explore deep into the delta. The camps have excellent horses, professional guides and lots of support workers. They have a reputation for providing a great riding experience.

The morning ride, when the guides take you to beautiful, shallow lakes full of water lilies, tends to be more active. It is unlike any other riding experience. With rainbows forming in the splashing water around you and the sound of huge drops of water bouncing off your body and face,it is truly exciting. You are very likely to come across large wild animals, too. On horseback it is possible to get quite close to elephants, giraffes and many other animals. The sense of excitement and tension levels rise suddenly though, as does your heart rate, as you move closer to them.

In the evening, rides are usually at a more relaxed and unhurried pace, with golden light streaming across the grassy delta and the animals coming out to eat and drink. Sedate though they are, rides at this time of day are still very impressive. As the sun's rays pass through the dust kicked up by the horses, the romance of Africa comes to life.

Back at the camp you can kick off your boots and enjoy excellent food and wine. Looking back on your day, you will find it hard to deny that a horseback Safari is as close as you will ever come to answering the call of the wild.
